Cervical Examination

From Physiopedia

Contents

Subjective

Patient Intake

Self‐report

Taking a detailed patient history is important. Listen carefully to the patient’s past medical history (PMH) and history of present illness (HPI). The narrative given by the patient contains much of the information needed to rule out red flags, and guide the cervical examination.

Neck Disability Index[1]

  • Contains 10 items (7 related to ADLs, 2 related to pain, 1 related to concentration)
  • Each item is scored 0 – 5 and the total score is expressed as a percentage
  • Higher scores correspond to greater disability
  • Minimal detectable change is 5 (10%).
  • MCID is 9.5 (19%)—Cleland and colleagues for patients with mechanical neck disorders
  • Moderate test re-test reliability 
  • Valid health outcome measure in Pts with cervical radiculopathy
  • ICC for test re-test reliability = 0.68
  • MCID is 19-20 percentage points

The Patient-Specific Functional Scale[1] (PSFS) for patients with neck pain 

This self report is a practical alternative supplement to generic and condition-specific measures.

  • Asks patients to list 3 activities that are difficult as a result of their symptoms/injury/disorder
  • The patient rates each activity on a scale of 0 – 10;0 represents inability to perform the activity and 10 represents the ability to perform the activity as well as they could prior to the onset of symptoms
  • The 3 activity scores are averaged for a final score
  • ICC test re-test reliability in patients with cervical radiculopathy is 0.82
  • MCID is 2.0 points

Performance‐based outcome measures[1]

Movement or activity limitations associated with the patient’s neck pain and be used to assess the changes in the patient’s level of function over the episode of care. These activities should be measureable and reproducible. This is commonly referred to as an asterisk sign. Have the patient perform an activity that produces their symptoms such as looking over their shoulder as if they were checking a blind spot when driving, and note at which point in the motion symptoms are elicited. After intervention this can be reassessed to see if symptoms are decreased, or range of motion is gained which would indicate an improvement in function.

Region‐specific historical examination

When taking the patients history it is important to ask if they have pain or symptoms in other regions such as their thoracic spine or shoulder.

Special Questions

• Patients with neck pain should be questioned for the presence of red flags.
• A thorough medical history and the use of a medical screening form is the initial step in the screening process.
• The chart below highlights some of the most common red flag conditions for patients with neck pain.

• Screen for cervical spine fracture. If there has been trauma, follow theCanadian C-Spine Rule.               

Yellow Flags

Yellow flags are factors that increase a patient’s risk for developing long-term disability. The Fear-Avoidance Beliefs Questionnaire (FABQ) is a tool to assess yellow flags among patients. The FABQ predictive validity is debatable, and is best for the FABQ-W when evaluating workers compensation patients.  The overall test-retest reliability is excellent, ICC= .97.

Some attitudes and beliefs to look out for are[2].

  • Pain is harmful or disabling 
  • Pain must be eliminated before returning to activity
  • Passive attitudes towards therapy 
  • Patient utilization of extended rest, reduced activity level and withdrawal from daily activities
  • Patient reports of extreme pain intensity
  • High intake of alcohol or other substances

Psychosocial factors

May be contributing to a patient’s persistent pain and disability, or that may contribute to the transition of an acute condition to a chronic, disabling condition[2].

Depression screening

Screening tools such as the Beck Depression Inventory (BDI) or the Depression Anxiety Screening Scale (DASS) are useful in screening patients for depression.

Psychometric properties of the BDI: a cut-off score of ≥5 for screening, Sn = 90.9%, Sp = 17.6 %. A cut-off score of ≥22 for diagnostic utility, Sn = 27.3%, Sp = 90%.

Pain catastrophizing

The Pain Catastrophizing Scale, helps determine if the patient is exaggerating their pain and symptoms and the severity of the situations as a whole. Cronbach alpha values reported for the total Pain Catastrophizing Scale (PCS) (α=.87) and factor scales(Rumination α=.87; Magnification α=.60; Helplessness α=.87) were found to be satisfactory. The total PCS score showed strong temporal validity[3].

In a patient population with acute whiplash there was found to be a significant moderate correlation between pain pressure threshold and the pain catastrophizing scale as well as cold pain threshold and the pain catastrophizing scale[4].

Investigations

Radiological Considerations: 

  • Diagnostic Imaging Considerations: see Canadian C-spine Rules.  If patient is positive on the rule a referral for imaging is required.
  • Cervical spine radiograph are most commonly utilized to assess for fractures; however cervical CT is more sensitive for ruling out fractures. Patients with rapidly worsening neurological signs and symptoms should be referred for a cervical MRI.
  • Patients with red flags including a history of cancer, possible cervical arterial disease, and possible instability should be referred for diagnostic imaging procedures.

Objective

Observation

Posture

Observe the patient’s posture in standing and sitting.As a part of the examination, postural deviations can be corrected to determine the effect on the patient’s signs and symptoms.

Common postural deviations:

  • Protracted cervical spine or forward head posture
  • Protracted shoulder girdle and rounded shoulders
  • Upper Thoracic Spine
  • Kyphotic or Flexed
  • Lordotic or Extended
  • Normal
  • Middle Thoracic Spine
  • Kyphotic or Flexed
  • Lordotic or Extended
  • Normal

Movement Patterns

Functional Tests

[5]

Cervical AROM[1]

  1. Prior to movement testing the examiner asks the patient about baseline symptom location and intensity. The examiner notes any change in location or intensity during the testing and where in the motion they occur.
  2. The examiner should assess for the presence of symptom centralization and peripheralization during testing. Repeated motions may be utilized as part of this assessment.
  3. Neck flexion, extension, rotation and side-bending can be measured with an inclinometer
  4. All cervical AROM tests performed with the patient in seated in an upright posture
  5. Inclinometer cervical ROM measurements have exhibited reliability coefficients ranging from 0.66 to 0.84 (ICC).
  6. A universal goniometer is used to measure cervical rotation if measured in sitting.
  7. Passive overpressure may be applied at the end of active motion to assess for pain response and end-feel.
  8. Combined motions:

          • Upper cervical flexion and lower cervical extension is assessed with cervical retraction.
          • Upper cervical extension with lower cervical extension is assessed with cervical protraction.
          • The cervical quadrant involves combined cervical extension with ipsilateral rotation and sidebending.

[6]

Cervical and Thoracic Segmental Mobility[1]

  1. The patient is positioned in prone. Cervical and thoracic spine segmental mobility and pain response are assessed.
  2. The examiner contacts each cervical spinous process with the thumbs. The examiner applies an oscillatory posterior to anterior force.
  3. The examiner can assess mobility unilaterally by performing the same procedure over the cervical articular pillar on each side.
  4. The examiner assesses for pain provocation at each segment. 
  5. The mobility of the segments is judged to be normal, hypermobile, or hypomobile. Interpretation of mobility is based on the clinician’s perception and experience. 
  6. Psychometric data for combined pain provocation and mobility assessment:
    • Sensitivity = 0.82 (negative Likelihood Ratio = 0.23)
    • Specificity = 0.79 (positive Likelihood Ratio = 3.9)
  7. Pain ICC = 0.42 – 0.79 (For patients who have cervical neck pain)
  8. Presence of upper cervical Joint dysfunction in patients with headaches ICC = 0.78 – 1.0.

Passive OA Joint testing (flexion/extension)

Patient positioned in supine with head on or off the treatment table

  1. Therapist is in standing at the head of the patient
  2. Motion testing (Right OA joint)
    • Rotate head 20 – 30 to right side to orient the right facet into the sagittal plane
    • Translate occiput anteriorly on the superior facet of C1 to asses for OA extension restriction
    • Translate the occiput posteriorly to assess for OA flexion restriction.
    • Repeat to the Left side.
[7]

AA Mobility Testing (Cervical Rotation in Flexion)

  1. Cradle head with both hands
  2. Contact the posterior aspect of C1 with finger tips
  3. Flex cervical spine
  4. Assess amount of rotation to each side
  5. Maintain flexion while rotating

Palpation

Supine

  • Palpate bilateral sternoclavicular joints for mobility assessment or tenderness.
  • Palpate acromioclavicular joint for mobility assessment or tenderness.
  • Palpate suboccipital muscles, upper trapezius, levator scapula and pectoralis minor to assess shortness or   tenderness.

Prone

  • Central and peripheral Cervical and Thoracic Spine
  • Palpate ribs 1 – 7 of the upper and mid thoracic region
  • Ribs 1 - 7 posterior to anterior accessory motion

Seated

  • Palpate for tissue texture changes down medial groove of cervical and thoracic spine
  • Palpate for tissue texture changes on either side of the spinous processes of the cervical and thoracic spine
  • Palpate for any scoliotic deviations

Neurologic Assessment

A neurological examination should be performed if the patient reports numbness or tingling in the back, shoulder, or more distal upper extremities, or if the patient has focal weakness that would indicate nerve involvement1.

[8]

Reflexes[2]

Cranial Nerve Assessment[10]

  • Vestibular and Optic cranial nerve screen for cranial nerves 2,3,4,6 and 8
    • Snellen Eye Chart to test visual acuity
    • Test each eye separately (covering the untested eye); test at a distance of 20 feet. O’Sullivan, Chapter 8, Examination of motor function
    • Pupillary reaction, (constriction) is tested by shining a light in the left eye and right eye. If there is an absence of constriction this indicates abnormal function of the optic or oculomotor nerve.
    • Extraocular movements are tested by asking the patient to follow a moving finger in a horizontal, vertical and horizontal plane. If they eyeball deviates from it’s normal conjugate position, eye movements are impaired or the patient reports double vision, there is dysfunction of the oculomotor, trochlear and/or abducens nerve(s).
[11]
  • Trigeminal Nerve
    • Sensory: Test noxious and light touch sensations on forehead, cheeks and jaw of the patient. Loss of facial sensations or numbness are reported with a trigeminal nerve lesion
    • Motor: Test the muscles of mastication by asking the patient to clench their teeth. Weakness, wasting of muscles or unilateral jaw deviation indicate a trigeminal nerve lesion.
  • Facial Nerve
    • Facial expression is tested by asking the patient to raise eyebrows, frown, show teeth, smile, close eyes tightly and puff out both cheeks.
    • Paralysis is indicated by the patient’s inability to close eye, drooping corner of the mouth or difficulty with speech articulation.
  • Unilateral LMN: Bell’s Palsy (Peripheral nerve injury)
    • Bilateral LMN: Guillain-Barre
    • Unilateral LMN: Stroke
  • Glossopharyngeal and Vagus and Hypoglossal nerve
    • Listen to voice quality and articulation
    • Dysphonia: Hoarseness denotes vocal cord weakness; nasal voice quality indicates palatal weakness.
    • Dysarthria: Poor speech articulation.
  • Spinal Accessory Nerve
    • Have the patient shrug both shoulders upward against resistance. An inability to shrug bilateral shoulders upward against resistance may indicate a lesion to the spinal accessory nerve.

Movement Testing

  • AROM, PROM, and Overpressure
  • Passive Intervertebral Motion
  • Muscle Strength

Special Tests

[12]

Cranial Cervical Flexion Test[1]

  1. The patient is positioned in supine in hook lying with the head and neck in mid-range neutral. Towels may be needed under the occiput to achieve this neutral position.
  2. A pneumatic pressure device, such as a pressure biofeedback unit, is inflated to 20 mmHg to fill the space between the cervical lordotic curve and the surface of the table.
  3. While keeping the occiput stationary (not lifting or pushing down), the patient performs the CCF in a graded fashion in 5 increments (22,24,26,28 and 30mmHg) and aims to hold each position for 10 seconds. 10 seconds rest is provided between stages.
    • CCF is performed by the patient gently nodding the head as though they were saying “yes” with the upper neck. This motion should flatten the cervical lordosis and subsequently change the pressure in the pneumatic device.
    • While the patient is performing CCF, the therapist palpates the neck to monitor for unwanted activation of more superficial cervical muscles such as sternocleidomastoid. 
    • The test is graded according to the pressure level the patient can achieve with concentric contractions and accurately sustain isometrically.
    • The test is terminated when the pressure is decreased by more than 20% or when the patient cannot perform the proper CCF movement without substitution strategies.
  4. A normal response is for the pressure to increase between 26 – 30 mmHg and be maintained for 10 seconds without utilizing superficial cervical muscle substitution strategies.
  5. An abnormal response is where the patient:
    • Is unable to generate an increase in pressure of at least 6 mmHg
    • Is unable to hold the generated pressure for 10 seconds
    • Uses superficial neck muscles to accomplish the CCF or
    • Uses a sudden movement of the chin or pushing (extending) the neck forcefully against the pneumatic pressure device.
  6. ICC = 0.81, performance index ICC = 0.93

Neck Flexor Muscle Endurance Test[1]

  1. The patient is positioned in supine, in hook lying. The chin is maximally retracted and maintained isometrically while the patient lifts the head and neck until the head is approximately 2.5cm (1 in) above the plinth while keep the head retracted to the chest.
  2. The therapist focuses on the skin folds along the patient’s neck and places a hand on the table just below the occipital bone of the patient’s head. The therapist gives verbal commands such as “tuck your chin” or “hold your head up” whenever the skin folds begin to separate or the patient’s occiput touches the therapist’s hand.
  3. The test is terminated if the skin fold(s) is/are separated due to loss of chin tuck or the patient’s head touches the clinician’s hand for more than 1 second.
  4. Reliability
    • Subjects without neck pain: ICC = 0.67 – 0.91, SEM 8.0 – 15.3 seconds
    • Subjects with neck pain: ICC = 0.67, SEM 11.5 seconds
[13]

Upper Limb Tension Test (ULTT)[1]

  1. The patient is positioned in supine. During the ULTT that places a bias towards testing the patient’s response to tension placed on the median nerve, the examiner sequentially introduces the following movements to the symptomatic upper extremity.
    • Scapular depression
    • Shoulder abduction to approximately 90 degrees with the elbow flexed
    • Forearm supination, wrist and finger extension
    • Shoulder lateral rotation
    • Elbow extension
    • Contralateral then ipsilateral cervical side-bending
  2. A positive test is indicated by the presence of any of the following findings:
    • Reproduction of all or part of the patient’s symptoms
    • Side-to-side differences of greater than 10 degrees of elbow or wrist extension
    • On the symptomatic side, contralateral cervical side-bending increases the patient’s symptoms, or ipsilateral side-bending decreases the patient’s symptoms
  3. Sensitivity = 0.97
  4. Specificity = 0.22
  5. + Likelihood Ratio = 1.3
  6. -Likelihood Ratio = 0.12
[14]

Spurling’s Test[1]

  1. The patient is seated and asked to sidebend and slightly rotate head to the painful side.
  2. The clinician places a compressive force of approximately 7 kg through the top of the head in an effort to further narrow the intervertebral foramen.
  3. The test is considered positive when it reproduces the patient’s symptoms. The test is not indicated if the patient does not have upper extremity or scapular region symptoms.
  4. Sensitivity = 0.50
  5. Specificity = 0.86
  6. + Likelihood Ratio = 3.50
  7. –Likelihood Ratio = 0.58

Distraction Test (used to identify cervical radiculopathy)[1]

  1. The patient is positioned in supine.
[15]
  1. The examiner grasps under the chin and occiput, flexes the patient’s neck to a position of comfort, and gradually applies a distraction force of up to approximately 14 kg.
  2. A positive test occurs with the reduction or elimination of the patient’s upper extremity or scapular symptoms. The test is not indicated if the patient has no upper extremity or scapular region symptoms.
  3. Sensitivity = 0.44
  4. Specificity = 0.90
  5. + Likelihood Ratio = 4.40
    • – Likelihood Ratio = 0.62

Valsalva Test[1]

  1. The patient is seated and instructed to take a deep breath and hold it while attempting to exhale for 2 – 3 seconds. #A positive response occurs with reproduction of symptoms.
  2. Sensitivity = 0.22
  3. Specificity = 0.94
  4. + Likelihood Ratio = 3.50
  5. – Likelihood Ratio = 0.83

Differential Diagnosis

3 diagnostic questions[16]

  1. Are the patient’s symptoms reflective of a visceral disorder or a serious or potentially life-threatening illness? This may indicate non-mechanical conditions such as:
    • Cervical Myelopathy
    • Cervical Instability
    • Fracture
    • Neoplastic conditions
    • Vascular compromise
    • Systemic/visceral disease
  2. From where is the pain arising?
    • The therapist seeks to understand characteristics about the pain source and thus select appropriate tests and measures early in the physical examination to rule out conditions.
  3. What has gone wrong with this person as a whole that would cause the pain experience to develop and persist?
    • The therapist considers what other variables are present that serve to maintain or perpetuate the pain experience such as depression, passive coping, central pain hypersensitivity, and fear.
